Solution 1

Well, I'm not sure if you want help, because if you did, you'd surely post some code ? Your timer will keep firing until you stop it. So, stop the timer firing as the first line of your event ( it also has a property as to if it will fire more than once, but I always turn them off in the event, to be sure ). But, I am guessing as to what the cause is, based on the lack of info you provided.

can you post some code?
I don't know howw you code. but you can reference the following:
int flag =0;
code into evetn timer:
if (flag=0)
{
// execute your query
flag = 1;
}

I hope that this way will usefull for you.

Good lucky!

Why did you comment to me and not the OP ? Your code doesn't look remotely useful in any case, but....

i dun think that's gonna work , i'm doing an operation every 1 minute,i want the program to execute the method 1 time every minute but the timer execute it 2 times every 1 minute

You've still not posted code, so I doubt you really want help. I suspect then that you've assigned the tick event twice, so it's called twice. Again, we're guessing because you don't want help enough to show us your code.

Solution 2

try moving your method out of the timer tick event

C#

Timer MyTimer = new Timer();

MyTimer_Tick(object sender, EventArgs e)
{
MyTimer.Enabled = false;
DoMyAction();
}

void DoMyAction()
{
//do you actions here
MyTimer.Enabled = true;
}
